To ,all whom 'it may concern.-

Be it known that I, WILHELM Mronnmr, a subject of the King of Saxony, and a resident of Deuben, neel Dresden, in the Kingdorno Saxony, Germany, have invented certain new and useful Improvements in Steam Lubricating Apparatuses, of which the. followingis a iull, clear, and exact description.

,This invention relates to a steam lubricatro ing apparatus for steam cylinders and valyes of all 1nds,in which the expulsion of the oil is operated byA the water of condensation accumulating in the chambers of the same.

The task to be soiyed by the present invenz 5 tion is on the one hand, to better insure a uniforni thoroughly mixing the oil and the steam and on the other hand, to afford a relief of the pas-V sage leading from theglass chamber to the zo steam-pipe, and also to revent the suction of the water from the g ass chamber arisingY from sudden fluctuations in the (pressure of the steam which varies in its spec This steam lubricating apparatus is shown a5 in the accompanying drawings, Figures 1 and 2 being sections of it taken at right angies to one another. Fig. 3 is a vertical and horizontal section of a form of constmction of an adustably arranged iattice-shaped nii-dis-V tri uter in the steam and oil ipe. Figs. 4 to 10 show in sections and en views forms of construction of the oil-distributors arranged in the throttle-nozzles and the kind of narrow passages'hereby formed.v Figs. 11 to 14 are sections and end views of forms of construction of throttle-nozzles in which the nar- .row assages are directly arranged in these nozz es Without the use of separate insertions. 4o The glass chamber i instead of, as hitherto, being connected with the steam-pipe by .merely one assage Y2 is Yconnected by another passage 3, ig, 1, placed higher than the passage 2, or by several such assages, so that thereby the passage 2 for t Ve iow of the oil and water from t e lass chamber 1 to the steam-pi e is relieve the passage 2 having merely t e object of servin for the running ofi' of the oil and Water, w ile the water of 5o condensation formed in the upper convexity of the 'wall of the steam-chamber just above the pas'sfge 3, which a Vein replaces the Water carried ber 1, can pass by the passage 3 into the glass 5 5 chamber. This Warm Water of condensation which is discharged into the glass chamber distribution ofthe oil for the purpose ofi* Ytraiter contained in the with the oi from the glass charca` through Ythe 'assage 3, penetrating the surface-level of the eil, does not come 1n contact with the oi owing ofi' through the passa e 2, so that a disintegration of the latter by oiiing and an inuryto its lubricating action isY Vpreyented an the water of condensation con-V tained in the lass chamber is not rendered impure. It mit thus be seen that the passage 2 can oniyserve for the flow of the oil and Water out from the glass chamber and not for the introduction into the said chainber of the waterof condensation formed in Vthe steaznrhamber 7 which water of condensation has to replace the water in the Yglass chamber which is carried ed with the bil. 0f course or that purpose onl that Water of condensation can beV used w ich is formed 1n the upper convexity of the well of YVth'e5steam-chamber 7 just above the higher passage 3 'and which runs downward to said 'passa e, through which it flows into the glass cham er. Further, in order to prevent the Y y lass chamber 1 bein1 Vdrawn out of the cham er by the action o the steam flowing through the apparatus, thus causing intermptions in the oil-supply, one or more of the passages 2 3 is or are prolonged by a tubuiar rejection 4, which extends toward a tabu ar ieee 6, closed atits rear end and referab y displaceable by means of a spin le 5, which piece 6 proiects somewhat beyond the tubular projection 4. .A chamber 7 is formed by means of this tubular piece 6, in which chamber the steam accurnuiating therein undergoes cooling andY exerts a certainYV ressure against the passage 2, Yrovided Witf the tubular projection 4, an' 'also against the higher-placed passage 3 which pressure consequently nenti-alizee the suction action produced by the steam-passage on the water contained in the glass chamber, while not impeding the upward rising through the Water and drawin oif of the specifica ly lighter drops of oil. e tu- 'buiar rejection 4 also revente impurities cerriedgalon on the Wal s of the steam-pipe from being orced into the lass chamber 1.

. further object ofthe cham er 7, formed by the tubular piece, consists in that the cooled steamV contained therein itself collects the oil i entering the chamber and distributed therein without decom osition of the oii by heat havi to be feareld, as would be the case if the oi were directly introduced into the steampassage itself through steam of a normal degrec' of heat. There thus takes piace e per- IIO 4whichstops u the passages.

In orderto vetterinsure the uniform mix?A ture of the forced oil with the steam-pass' throu h the ap aratus and to reven't acolcxilg.- in o the oil y .the water o `-condensation w 'ch has cooled and is contained in the. ipe or passa e, the oil-distribution is. operate? Dy means o a lattice-work, a'perforatedaplate,

or. thelike 9, Fig. `2,;inserted@between the place where the steam and oil pipes meet, and a throttle-nozzle..8.. Thislattlce, plate, or the like may-preferably also becombined with the nozzle 8in order to be able to be removed With the latter for the urposeof be-4 ing cleaned. The oil passing fir) ing-place l0 of the steam'and oil pipes does not come in contact with the. wall1of the part of the pipesituated in front `ofthe lattice- Work 9, .arranged in immediateproximityto this meeting-place, but it strikes about. the middle of the surface of the lattice and.- then runs along thebars of the-same, so 'that it covers the entire lattice, and thusthe steam, which by the action ofthe throttlesnozzle is under pressure, on flowing through the lattice-work -encounters oil everywhere at the narrow passagesof said lattice-work, and is thereby thoroughly mixed with the said oil. When the steam has once absorbed .the oilit no longer releases it, and there is therefore no fear that the oil Will remain adheringtoi the walls of the Wider.- passage or pipe without being caught along with the steam. Im consequence of the mixture of theoilwith fthe hot steam the oilcan also exert-its luhrieatf ing action `in a heated condition withoutcoming in contact with cooled watenotcondensation and having to undergo .throughfthis latter a cooling or any otherwise deleterious action.

From the foregoing it willbe observed that the generaloperation ofthe lubricator may bebrieily noted, as follows :1V a desi ateslthe condenser, in4 which the steam received from the boiler is formed into -Water of condensa-i tion, which flows through the .main central Water-tube b into thebottom oil-reservoir c.

In Fig. 1 1 the periorations or narrow 14d, provided directly in the thrott e-nozzie 8, radiate or converge toward the lubricating-place or in such a way that they extend into the narrow passage 15b or proceedgshere from in a reverse direction and extend radiatingiy toward the meeting-place of the oil and the steam. Instead of opninig into the narrow perforation of the t ott e-nozzle these narrow passages 14 may also directly open onto the side oi the nozzle 8f, facing the lubricating-placein the oil and steam pipe, as shown in'Fi 12, or the assages 14 ma be formed in t e end of t e nozzle 8 an extending in the latter parallel to one another and standing in communication with the narrow perforation 15 b means of an intermediate space 19, provi ed in the interior of the nozzl as shown in Fig. 13. Finally, the thrqttleozzles 8h may also themselves have at the end facin the 'meetinglace of the steam and oil a s ofi-shaped peroration 14, as shown in Fig. 14, serving as a narrowA passage-way to the nozzle-perforation 15d. Instead of one auch slot several may also he provided, arranged crosswise to one another or in any other suitable manner. Having now described my invention, what I claim as new, and desire to secure by Letters Patent,
